Deposition of Atmospheric Nitrogen Species to Forests in North America and Europe: Foreign Trip Report, September 24-October 11, 1989.

摘要

The traveler was invited to (1) present an invited seminar at the Juelich Nuclear Center, (2) visit the Landesanstalt fuer Immissionschutz for the State of Nordhein-Westfalen, (3) visit the Institute for Bioclimatology at the University of Goettingen, (4) present an invited plenary lecture at the International Congress on Forest Decline, and (5) visit field sites operated by the University of Freiburg. At Juelich, the traveler presented a joint seminar to the Institutes of Atmospheric Chemistry and Radioagronomy on ''Deposition of Atmospheric Nitrogen Species to Forests in North America and Europe.'' At LIS, he visited the Egge Mountains field sites for discussions of deposition measurements. At the University of Goettingen, where the traveler was on sabbatical assignment during 1987, the progress of joint research was discussed and manuscripts finalized. At the Congress on Forest Decline, he delivered an invited plenary lecture on ''Rates of Wet, Dry, and Cloud Deposition to American Forests'' and went on an excursion to the Hoeglwald Forest and Frauenhofer Institute research sites. At the University of Freiburg, he visited field sites in the Black Forest where deposition/nutrient cycling research is performed.
